OMC Cobra trim problem
 

The trim on this boat will not go up or down. I've checked the power feeds and
grounds and they are fine but all I get are clicks at the part pictured below.

This looks a little different from the trim solenoids I've replaced in the past
but I'm assuming it's just a sealed unit that does the same thing.

Does anyone know the name of this part?

Do these things commonly fail? I'm having a hard time finding the part on the
internet.

Can I test the pump by bypassing this part - the pump has a Blue and Green wire
going to it.

Touch 12V to the blue lead the pump should activate and the drive moves
up. 12V to green should make the drive go down. That thing with the
circuit breaker might be a combo device with solenoids and breaker.
You'll figure it out.

OOPS! Hit too soon.

the pump motor , that is if it's a magnet field motor. your two wires
go to the brushes Possible to put positive on one wire, and neg. to
the other. Motor should run one direction, change the polarity and it
will run the other direction. That rule usually applies to magnet
motors though. Like an automotive window motor

Tim,

I was wondering where/how the motor was grounded but if you're correct, that
would make sense that there are just 2 wires and no obvious ground.

I'm going to test it in the morning but I wonder if I can do any damage testing
it like you describe.

The part I attached a photo of is called the Relay and Circuit Breaker Assembly
and cost close to $300. If the trim pump motor tests OK then the Relay Assembly
must be bad.

I'm learning that boats are like cars - sort of.

Thanks for your help
Larry

I have repaired some trim relays in the past. Usually you have to unbend
tabs and things to get them open. Typically there is plenty of contact left
and clean up with a file will fix them. Ohm out the windings first cause if
one of them is open then you'll have to replace it.
